Method of making ink roller assembly

Abstract

There is disclosed an ink roller assembly and a method of making an ink roller assembly. The assembly includes a base comprised of closely spaced connected discs providing capillary chambers and a porous sleeve. The method uses air to expand the porous sleeve while the sleeve is being slipped onto the base.

I claim: 
     
       1. Method of making an ink roller assembly, comprising: providing a generally cylindrical elongate base having a series of closely spaced connected discs defining a series of capillary chambers, providing a porous tubular sleeve with an inside diameter smaller that the outside diameter of the base, manually slipping the sleeve part way onto the base without the use of air to partially assemble the sleeve onto the base, thereafter using a nozzle to apply air under pressure between the partially assembled sleeve and base while slipping the sleeve further onto the base, and inking the sleeve and the capillary chambers of the base. 
     
     
       2. Method of making an ink roller assembly, comprising: providing a generally cylindrical elongate base having a series of closely spaced connected discs defining a series of capillary chambers, positioning the base generally vertically in a holder, providing a porous tubular sleeve with an inside diameter smaller that the outside diameter of the base, manually slipping the sleeve part way onto the base, thereafter inserting a nozzle down into the sleeve and expanding the sleeve by use of air under pressure from the nozzle to between the sleeve and the base while slipping the sleeve further onto the base, removing the assembled base and sleeve from the holder, and inking the sleeve and the capillary chambers of the base.
